yThis invention relates to glass` globes of the character generally employed around gasoline filling stations, and which globes are generally of a drum shape, havingtwo exposed, outwardly convexed facescarrying action destroys the advertising matter after a short period of time, wherefore any diminution of the gloss or highlights incident to portrayal of advertising matter upon they outer faces lof"y the display panels, while somewhat solving the problem, is not ,commercially practical, .because of the early deterioration of the advertising displayby the elements. .f f

This invention concerns itself with the vre-` y duction of the gloss or the high lights lon globes of the characterunder consideration.

The invention is explained as applied to Y' globes that carry the `advertising matter beneath the outer exposedsurfaces of the .glass panels of such globes.:` The glass panelsare treated upontheir outer vsurface in theinane' "ofi the acid, and 'they'are Ajthen. dried.' vv`rlhfey;`

The glass panels 15 .are mounted upon the globe 10, for example, as shown herein and in the indicated ,application tov Mattmann.y

- Each panel 15, before mounting thereof on the globe, is immersed in a bath of hydro l'luoric acid, with the face 30 thereof disposed upwardly while in such bath.` `The face 30 which iszafsverii No. 269,094.1

as shown herein and in theindicated Mattmann application, and-the treated panels-'15 sofa:

may be placed over the advertising matter, to protect same from the elements. The panels 15 When treated as disclosed herein, are sufliciently transparent topermit clear and distinct display or observation of the advertising matter through the treated.v faces of the glass panelsfduring either the day :or

night seasons. 4`lt isito he understood that the y globes are illuminated at night, by ffneans 'of `an electric .lamp y19, placed inside -zthe' globe 10. The treated facesBO of the glass panels l5 apparently effect a refraction or subduing of light rays to such anextentithat the glare or high lights are substantially eliminated, and are reduced to such-extent that they become inconsequential factors.

Thereference `numerals in the accompanying drawings correspond With the reference A characters'inthe dra-Wing of the application of ,Mattmanm aforesaid. The Apanels 15 `when treated ont-heir outerinner faces, in `the manner described herein, areglven the vappearance of ground surfaces.
